Internally perl sure has pointers.  Every scalar is represented by a
pointer to a structure called an SV, which contains various info
depending on if it's a string, float, etc.  When the scalar is a named
or my variable even more pointers are involved.

Pointers are everywhere, just not where you can play with them at the
language level :)
